Due to special geographic situation, Iran is always exposed on different kinds of
natural and unnatural dangers and imposed by heavy financial (property) damges and
human (life) loss [1]. Fire is one of the oldest disasters which can endanger the property
and health of people during a short time. When the fire continues for a few days;
especially in forests, it will be caused to destroy several hectares of these pastures [2].
According to the available statistics, during just 10 last years, 13832 fires were
reported in natural fields of Iran which caused to deteriorate 142941 hectares of natural
regions of the country and resulted in high material damages (loss) [3]. One of cases
which is usually calculated after fire occurrence in the forests, is the remaining loss
which its appropriate assessment is high dependent on the correct estimation of the
burnt regions area [4].
In this research, by exploiting the image processing techniques, it was attempted to
measure the area of the burnt regions in aerial image after forest fire occurrence [5].
Also, in section 2 of this paper, a background of similar studies and the present
research in field of forest fire are examined [4-10]. In sections 3 and 4, after
segmentation and noise cancellation in the sample image, the primary area of the burnt
regions is calculated by two methods of, integration and the extraction of interconnected
components [11-14]. In section 5, measurement of imaging scale to calculate real area
[15] and in section 6, the analysis of results are discussed. In final section, the
conclusions of the performed research are presented.
